苹果手机不解析微信客服消息中的a标签

Question

微信发送的公众号客服消息，苹果手机无法解析a标签，安卓可以，但苹果手机点进去查看也是正常的

$text="<a href='".$_W['siteroot'].'app/'.substr($this->createMobileUrl('detail',array('id'=>$id)),2)."'>恭喜您！活动【".$hd['hdname'].'】'."报名成功，点击查看报名详情！";

                            $text=urlencode($text);

                            $access_token = WeAccount::token();

                            $data = array(

                                "touser"=>$temp_member['from_user'],

                                "msgtype"=>"text",

                                "text"=>array("content"=>$text)

                            );

                            $url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token={$access_token}";

                            load()->func('communication');

                            $response = ihttp_request($url, urldecode(json_encode($data)));
